Zeev, I'll repeat for the last time, if you look at the micrographs and X-ray diffraction of OUM material, one phase is definitely crystalline, the other definitely amorphous, ergo, this is a FIRST order phase transition, thus there is an enthalpy of transition (just like the heat of fusion between water and ice), it is of course much smaller than that of water (water happen to be the largest enthalpy of transition I know of.). That is problem 1. Problem two is that the "traditional" theory of embryionic nucleation (in homogeneous nucleation of a crystalline phase from an amorphous phase) theory breaks down as the dimensions of the material become closer to "two dimensional" (as will have to be the case to reach extremely high cell density). Sorry to make you repeat yourself. I'm completely ignorant regarding phase-change technology, but damn interested, so I'll have a more educated response for you next time -- either through my own researches or from someone at Ovonyx. Thanks for taking the time, wily
